Only two years later did Xu Changxing slowly open his eyes.
He still felt he had not had his fill, but he had thoroughly digested his gains this time and could glean no further insights.
With a trace of regret, Xu Changxing entered seclusion to condense upper-grade immortal essence stones.
Over the following decades, he ran more than ten simulations in succession.
Each followed much the same course. During the first half of his time in the Tianyan Sect, he accumulated sect contribution points by refining pills.
For the next several hundred years, he explored the Abyss.
As he watched the scenes from the simulations again and again, his understanding of the Way of Slaughter improved rapidly.
Eventually, he could keep exploring the Abyss until the seven hundred and second year.
He had slain every demonic beast within tens of thousands of miles at least several times.
Perhaps because he kept studying the same rule fragments, he gained fewer insights each time he watched a simulation.
Fortunately, by then, he had attained a preliminary understanding of the Way of Slaughter.
Even without Daoist Wuchen's Rule Jade Pendant, he could resist the erosion of the Abyssal Rule to a certain extent.
If he wished, he could already attempt to break through using the Way of Slaughter.
But the Way of Slaughter was still not Xu Changxing's goal.
Although the Way of Slaughter was good, it still fell short of the Way of Destruction.
He had chosen to comprehend the Way of Slaughter first only because it was easier to grasp and would let him venture farther into the Abyss.
Now that his combat strength had improved again, he could explore deeper into the Abyss to comprehend the Way of Destruction.
Having made his decision, Xu Changxing started another simulation.
